We characterized 205 multiple-termination negative cloud-to-ground (CG) lightning flashes that were imaged by the Fast Antenna Lightning Mapping Array (FALMA) in Japan during the summer of 2017. The parameters we used included termination number, termination distance, fork height, return stroke (RS) number, the interval between the first RS of each termination, the shortest time difference between the strokes at different terminations, and the first RS intensities separated by termination occurrence orders. It was found that the multiple-termination flashes (MTFs) had a termination number rang

Abstract:

This essay argues that Emily Dickinson’s poetry intervenes in the broad cultural assessment of epistemology provoked by the evolutionary debates of the 1860s. While scholars have begun to explore the thematic correspondences between Dickinson’s poetry and some aspects of this cultural conversation, this essay examines the ways in which her intervention occurs at the level of poetic form and is in fact profoundly dependent upon form. Specifically, it analyzes a set of her poems from the early 1860s through the early 1870s in which she uses the dual structure of metaphor to elicit a way of think

Abstract Carbon fiber composite aircraft, has a special vulnerability to lightning. In the event of a lightning strike, the lightning current will cause local high temperature, and form a large area of delamination and fluffing, which will result in the reduction of structural strength.

But disconnecting the power supply during the heavy rain time creates unnecessary problems and accidents as well as leads to inefficient power management. Hence it is important to develop an intelligent system that can predict, alert and protect against lightning strikes.

Abstract. Lightning activity constitute the major destructive component of thunderstorms over India. Hence, an understanding of the long-term variability in lightning occurrence and intensity and their interrelation with various causative factors is required. Long-term (1998–2014) Tropical Rainfall Measuring Mission (TRMM) satellite-based lightning observations depict the most frequent lightning occurrences along the Himalayan foothills, the Indo-Gangetic plains and coastal regions, while the intensity of these lightning strikes is found to be strongest along the coastal regions and in the Bay

Abstract:

The study investigated the gas active arc extinguishing and lightning protection for transmission lines. Lightning is one of the most significant sources of over voltages in overhead transmission lines. The lightning over voltages could lead to failure of the devices connected to the transmission line. Fundamental constraint on the reliability of an electrical power transmission system is the effectiveness of its protective system. The role of the protective system is to safeguard transmission system components from the effects of electrical overstress. Shield wire and surge arresters are an i

Abstract:

Lightning strike, fire weather, and fire occurrence data were used to model (i) the probability that a lightning strike causes a sustainable ignition on the forest floor and (ii) the probability of an ignition being detected and reported to the fire management agency for each ecoregion in the province of Ontario. An index that tracks duff moisture content in very sheltered areas of a forest stand (near the tree boles) was the most significant predictor in each ignition model. The presence of positive cloud-to-ground lightning strikes was also found to have a significant and positive influence

Thunderstorm and lightning climatological research is conducted with a view to increasing knowledge about the distribution of thunderstorm-related hazards and to gain an understanding of environmental factors increasing or decreasing their frequency. There are three main methodologies used in the construction of thunderstorm climatologies: thunderstorm frequency, thunderstorm tracking or lightning flash density. These approaches utilise a wide variety of underpinning datasets and employ many different methods ranging from correlations with potential influencing factors and mapping th

The stability of ball lightning is analyzed. According to the electrodynamic model, the ball lightning consists of an energy core in the form of an ensemble of dynamic electric capacitors located inside a spherical shell of water. The dynamic capacitor consists of electrons and protons rotating in closed orbits. The shell tends to stretch under the force Fcf, which is, proportional to the kinetic energy of protons Ek, and the force Fel, proportional to the square of the uncompensated electric charge of the core Q2. The shell is compressed by the force Fsh proportional to its thickness a and th

Study of the ‘stone’ semantics of the nominative combination thunderbolt, which is most often used to refer to such a stone, has led us to the conclusion that the meaning of the lexical unit developed as a result of metonymic transfer of the name from an atmospheric phenomenon (lightning) to an object that was struck by lightning (stone). The mythologization of thunderstorms, thunder and lightning provided understanding of the stone thunde

Numerical field expressions are proposed to evaluate the electromagnetic fields due to the lightning channel with variable values of return stroke velocity. Previous calculation methods generally use an average value for the return stroke velocity along a lightning channel. The proposed method can support different velocity profiles along a lightning channel in addition to the widely used channel-base current functions and also the general form of the engineering current models directly in the time domain without the need to apply any extra conversions.

Abstract Lightning initiation and propagation is complex and probabilistic in nature. In this study, we attempt to replicate these phenomena using an electric circuit model. We reproduce lightning behaviors numerically by dividing an air column into discrete cells of resistor and capacitor components. First, we reproduce the attributes of classical tripole structure of electric field in thunderclouds. We represent charging mechanisms due to electrification and precipitation as current sources in the circuit. As a cell charges, the electric field increases to near dielectric strength limit caus
